This is one of the few serials in the original run of the series never to have been novelized through publisher Target Books. Target approached author Douglas Adams
on several occasions, but Adams (by then a bestselling author) was unwilling to work for the modest advance Target was offering to pay; Target, for their part, were unwilling to offer Adams a higher advance, for fear that other authors would demand more. Adams also refused to allow Target to have another author adapt his story. Adams also penned "Doctor Who: City of Death: Part One
(1979)" and the uncompleted serial "Shada", neither of which have been novelized for the same reasons. See more
